The NNTP server (nntpd) may be compiled in
two ways, depending on the expected load on the news system. There are no
compiled versions available, because of some site-specific defaults that are
hardcoded into the executable. All configuration is done through
macros defined in common/conf.h.

nntpd may be configured as either a standalone server that
is started at system boot time from an rc file, or a daemon
managed by inetd. In the latter case, you have to have the
following entry in /etc/inetd.conf:

nntp stream tcp nowait news /usr/etc/in.nntpd nntpd

The inetd.conf syntax is described in detail in Chapter 12. If you configure nntpd as standalone,
make sure that any such line in inetd.conf is commented
out. In either case, you have to make sure the following line appears in
/etc/services:

nntp 119/tcp readnews untp # Network News Transfer Protocol

To temporarily store any incoming articles, nntpd also needs
a .tmp directory in your news spool. You should create it
using the following commands:
